Andreas Kling a5bbe3280d LibGUI+WindowServer: Don't use a WM IPC to initiate own window resize
The WM_* IPC messages are intended for "outsider" window management,
not for a client's own windows. Make a separate StartWindowResize
message for this.

This was the only reason that every IPC client had to know its server
side client ID.
